OPINION SMITH, Circuit Judge. In 1986, David Munchinski was convicted of two counts of first-degree homicide and two counts of second-degree homicide arising out of a pair of murders that occurred in 1977 in Bear Rocks, Pennsylvania (the “Bear Rocks Murders” or the “murders”). In the years following his conviction, Munchinski discovered that prosecutors had withheld from his counsel almost a dozen articles of exculpatory evidence. After unsuccessfully petitioning for post-conviction relief several times in state and federal court, Munchinski filed a second or successive habeas petition pursuant to 28 U.S.C. §§ 2244 & 2254(d) in the United States District Court for the Western District of Pennsylvania. Munchinski argued that the Pennsylvania Superior Court unreasonably applied Brady v. Maryland, 373 U.S. 83, 83 S.Ct. 1194, 10 L.Ed.2d 215 (1963), when it declined to grant Munchinski postconviction relief based on several articles of exculpatory evidence that were unlawfully withheld by the prosecution. The District Court found some of Munchinski’s claims untimely under 28 U.S.C. § 2244(d)(1)(D), but equitably tolled the statute of limitations for a subset of those claims. The District Court next concluded that Munchinski had procedurally defaulted certain claims. The District Court excused his procedural default, finding that applying the procedural default doctrine to Munchinski’s petition would effect a fundamental miscarriage of justice. Finally, the District Court agreed with Munchinski that the state court had unreasonably applied Brady. The District Court granted Munchinski’s petition. Warden Harry Wilson and the Pennsylvania Attorney General (collectively, the “Commonwealth”) appeal from the District Court’s judgment. The Commonwealth concedes that it cannot “make a compelling argument” that the Superior Court properly applied Brady given the nature of the evidence that was withheld. Oral Arg. Tr. 4:8-9. We agree. The scope of the Brady violations here is staggering, and the Superior Court failed to appreciate the aggregate impact of the withheld evidence. In apparent recognition of that reality, the Commonwealth limits its appeal to three issues: (1) whether the District Court erred by equitably tolling the statute of limitations in § 2244(d)(1)(D); (2) whether the District Court erred by excusing Munchinski’s supposed procedural default on the basis of a fundamental miscarriage of justice; and (3) whether Munchinski has produced sufficient evidence “to establish by clear and convincing evidence that, but for constitutional error, no reasonable factfinder would have found the applicant guilty of the underlying offense,” 28 U.S.C. § 2244(b)(2)(B)(ii). We conclude: (1) that the District Court appropriately tolled the statute of limitations; (2) that Munchinski did not procedurally default his claims; and (3) that Munchinski has demonstrated his actual innocence by clear and convincing evidence, as is required by § 2244(b)(2)(B)(ii). “Section 2254(d) reflects the view that habeas corpus is a guard against extreme malfunctions in the state criminal justice systems, not a substitute for ordinary error correction through appeal.” Harrington v. Richter, — U.S. -, 131 -S.Ct. 770, 786, 178 L.Ed.2d 624 (2011) (internal quotation marks omitted). Like the District Court, we see precisely such an “extreme malfunction[ ]” in this case. Consequently, we will affirm the judgment of the District Court granting Munchinski a writ of habeas corpus pursuant to § 2254(d)(1). I. On December 2, 1977, Pennsylvania State Police found the bodies of two men in and around a cabin owned by Raymond Gierke in Bear Rocks, located in Fayette County, Pennsylvania. These two bodies were later identified as those of Gierke and James Peter Alford. The police notified Fayette County Deputy Coroner Jack Powell, who transported the bodies from the crime scene in order to conduct autopsies. Autopsies were conducted that same day by pathologist Dr. Sava Radisavljevic (“Dr. Sava”). On December 9, 1977, Dr. Sava delivered his autopsy report to the Fayette County Coroner’s Office. A week later, he delivered addenda to his report. The report and the addenda made clear that Gierke and Alford were shot multiple times at close range and died from their gunshot wounds. The report and addenda also suggested that both Gierke and Alford had been anally raped prior to the murders. The Pennsylvania State Police assigned Trooper Montgomery Goodwin as the lead investigating officer in the case. Trooper Goodwin worked with Corporal Robert Mangiacarne over the course of the next five years investigating the murders. Though Trooper Goodwin and Corporal Mangiacarne identified several suspects, they lacked sufficient evidence to file charges until 1982. A. At some point within the period of 1980 and 1981, Richard Bowen, a convicted burglar and forger incarcerated in state prison in Greensburg, Pennsylvania, contacted the Pennsylvania State Police claiming knowledge of the Bear Rocks Murders. The precise dates of the conversations between Bowen and the police remain unknown and the exact nature of those conversations remains unclear. What is certain is that Bowen’s statements were inconsistent and contradictory. Two of these inconsistencies are most remarkable for our purposes: (1) Bowen initially implicated only Leon Scaglione, the man who was eventually tried and convicted along with Munchinski; and (2) Bowen at first stated that he did not enter Gierke’s home during the shootings and did not directly witness the murders. There were numerous changes in Bowen’s account of the murders; at some point Bowen’s story changed such that he was a direct witness to the shootings, which he claimed were committed by Scaglione as well as Munchinski in a drug-related dispute. On October 22, 1982, Munchinski and Scaglione were charged with two counts of criminal homicide in violation of 18 Pa. Cons.Stat. Ann. § 2501(a), and two counts of criminal conspiracy to commit homicide in violation of 18 Pa. Cons.Stat. Ann. § 903. Munchinski and Scaglione were tried jointly in April 1983 (the “First Trial”). At this trial, the Commonwealth relied principally on Bowen’s purported eyewitness testimony. Bowen testified that he directly witnessed Munchinski and Scaglione commit the murders. Specifically, Bowen testified that Gierke and Alford were raped by Scaglione and Munchinski, respectively, and that the two victims were murdered almost immediately thereafter. Bowen’s trial testimony was markedly different from the stories he reportedly told police when he first approached them as a potential witness. Bowen’s testimony was also at odds with certain facts that were elicited at trial. For example, Bowen claimed that he drove Scaglione and Munchinski to the site of the murders in Scaglione’s lime green Ford Gran Torino. Scaglione, however, did not purchase that Gran Torino until almost six months after the murders. The Commonwealth also presented testimony from Lori Lexa and Deborah Sue Dahlmann. Lexa and Dahlmann, acquaintances well before their involvement in this case, claimed that Munchinski and Scaglione were with them in a bar in January 1978, and that Munchinski and Scaglione admitted to committing the murders. Dahlmann’s ex-husband Ed Wiltrout, however, was a prime suspect in the Bear Rocks murders; unbeknownst to Munchinski, at least one witness claimed to police that Wiltrout was one of the shooters. Munchinski was unable at trial to cross-examine Dahlmann with the witness statement implicating Wiltrout because the report documenting that statement had not been produced. The Commonwealth relied exclusively on testimony from Bowen, Lexa, and Dahlmann to link Munchinski to the crime, presenting no physical evidence linked to Munchinski. On April 12, 1983, the First Trial ended with a hung jury and the declaration of a mistrial. The Commonwealth dropped the conspiracy charges against Munchinski and severed Munchinski’s case from Scaglione’s case. In October 1986, the Commonwealth retried Scaglione. During his trial, Scaglione admitted to committing the murders. Scaglione testified that Munchinski had no involvement in the murders, but that Scaglione had committed the crimes with an associate named Homer Stewart who allegedly resembled Munchinski. Scaglione was convicted of two counts of first degree homicide and two counts of second degree homicide. In November 1986, the Commonwealth retried Munchinski (the “Retrial”). The Commonwealth’s case still consisted solely of witness testimony allegedly linking Munchinski to the murders. The Commonwealth again elicited testimony from Bowen, Lexa, and Dahlmann, which was largely consistent with their testimony from the First Trial. The Commonwealth also introduced testimony from two additional sources: (1) Bernard Furr, another acquaintance of Dahlmann’s, who repeated a story very similar to Dahlmann’s about an alleged confession in January 1978; and (2) Harold Thomas, who testified that Munchinski confessed while in jail in 1983. During the Retrial, Munchinski sought to introduce Scaglione’s testimony from his October 1986 retrial, where he implicated Stewart and exonerated Munchinski. Scaglione declined to testify, invoking his Fifth Amendment right against self-incrimination. Munchinski requested that the court grant Scaglione use immunity, but the court refused. Additionally, the trial court ruled that Scaglione’s prior testimony was inadmissible under Pennsylvania law. As a result, Munchinski was unable to introduce any exculpatory testimony from Scaglione. In his closing arguments, then-Assistant District Attorney Ralph Warman stated to the jury: “did you hear anyone testify that Bowen received anything other than immunity? No ... does that bolster his testimony to indicate that Bowen was there?” Munchinski App’x 42. This argument misled the jury. Unbeknownst to the jury and Munchinski, prosecutors in Fayette County had reached a leniency agreement with Bowen, whereby prosecutors in Westmoreland County would act leniently against Bowen in his ongoing parole revocation hearings in exchange for Bowen’s testimony against Munchinski. The Commonwealth failed to turn over to Munchinski documents evidencing this leniency agreement. Munchinski was found guilty of two counts of first-degree homicide and two counts of second-degree homicide. On June 15, 1987, Munchinski was sentenced to two consecutive life sentences, one for each of the first degree murder convictions. Munchinski received no additional penalties for the two second degree convictions. On July 14, 1987, Munchinski appealed from the judgment of sentence. On November 30, 1990, the Pennsylvania Superi- or Court affirmed. Commonwealth v. Munchinski, 401 Pa.Super. 300, 585 A.2d 471, 476 (1990). Munchinski then sought allocatur from the Pennsylvania Supreme Court. That court denied review on November 13,1991. B. In November 1991, while imprisoned in Oklahoma, Bowen asked to speak with the Federal Bureau of Investigation (“FBI”) about the Bear Rocks Murders. Bowen was soon contacted by FBI Special Agent Matthew Schneck. In talking with Agent Schneck, Bowen recanted his trial testimony, saying that “he was not involved in any fashion with Scaglione or Munchinski in the ... killings of Alford and Gierke.” Munchinski App’x 42. Munchinski was soon made aware of Bowen’s statement to Special Agent Schneck. On April 4, 1992, in response to Bowen’s recantation, Munchinski deposed Bowen. Bowen testified that he fabricated his trial testimony, and admitted that he was not in Pennsylvania on the night of the murders. Bowen claimed that police and prosecutors had threatened him. If he did not testify against Munchinski and Scaglione, Bowen said, “they would have someone come along and say that they were present and that I had done the shootings.” Bowen Dep. 13:7-9. Bowen maintained that Scaglione admitted to committing the murders, but that Scaglione “never did mention [Munchinski’s] name.” Id. at 21:15. Bowen also explained why his fabricated account of the murders changed over time. Specifically, he testified that he would rehearse his story with Trooper Goodwin, and that Goodwin would give him instructions: A: [Trooper Goodwin] asked me about the story, and I went over it, you know, a couple different times. And then, he started with “No, this is what happened” — you know— “and we have witnesses to verify this.” And, he started in with the [sic] I was driving the car and I told him, you know “[y]ou’re crazy. You people can’t prove none [sic] of this.” “We got witnesses.” And then, he started with a — he pulled a warrant out of hand — I never did see if it was signed or what it said— but he was reading on that where all he had to do is sign my name and I would be charged in the murder. Q: And, whenever this occurred, did Trooper Goodwin tell you that he wanted you to give him a different story? A: He told me the story, and then he said if I didn’t go along with that, then I would be charged in the homicide. Id. at 23:11-22, 24:4-9. Notably, Trooper Goodwin was responsible for the change between Bowen’s first account, when he claimed that he remained in the car, to his later accounts, when he claimed that he went into the cabin and directly witnessed the murders. Bowen claimed that he changed this part of his story because Trooper Goodwin “said that they had to have [him] in the house.” Id. at 61:16-17. Bowen further testified about how he prepared for trial with former District Attorney Gerald Solomon, the lead prosecutor during the First Trial: Q: And, did [Solomon] tell you what to say? A: Yes. Q: Did you tell him that you were not present at the killings? A: He knew I wasn’t. Yes, I told him that. I said, I — it was just a “I can’t do this, man. This ain’t right.” And, it’s — you know “[t]his is done all the time. We know they did it. We just — we have to put somebody there to say they seen them.” Q: And, that’s what he told you? A: Yes. Q: And, he knew that you weren’t there? A: Yes, he did. Id. at 42:7-20. Finally, Bowen described how he came to know so many details about the murders. He explained that Trooper Goodwin showed him several photos of the crime scene, and even took him to the scene and pointed out where the bodies were found. Bowen also confirmed that Trooper Goodwin gave him details about Scaglione’s lime green Gran Torino, and pressed him to include that information in his testimony; apparently neither of them was aware that Scaglione had not purchased his lime green Gran Torino until well after the murders. On April 16, 1992, only a few weeks after Bowen’s deposition, Munchinski filed his first petition for relief under the Pennsylvania Post-Conviction Relief Act (“PCRA”), 42 Pa. Cons.Stat. Ann. § 9541, et seq. (the “PCRA I” petition). The PCRA I petition sought relief based on two articles of newly-discovered evidence: (1) a September 1982 report from Trooper Goodwin (the “Goodwin Report”) that was intentionally edited to conceal a reference to a recorded statement made by Bowen; and (2) Bowen’s sworn deposition testimony. PCRA petitions are generally assigned to the judge who presided over a petitioner’s trial. In this case, however, the judge who had presided over the First Trial and the Retrial had retired from the bench, so the PCRA I petition was assigned to Judge William J. Franks of the Court of Common Pleas of Fayette County. Judge Franks held an evidentiary hearing concerning both of Munchinski’s evidentiary claims. Former prosecutors Solomon and Warman testified at the hearing about the Goodwin Report. Warman, the Commonwealth’s lead prosecutor during the Retrial, admitted that he intentionally edited the Goodwin Report to remove a paragraph referencing a recorded statement from Bowen, and spliced together the paragraphs before and after the removed text in order to conceal the removal. Warman testified that he intentionally removed the relevant paragraph because no statement from Bowen was ever transcribed or recorded and that the reference would be “misleading.” Solomon, who was Warman’s supervisor during the Retrial, corroborated Warman’s testimony. Judge Franks credited Warman’s and Solomon’s account, finding that Bowen’s statement was never recorded. Nonetheless, troubled by Warman’s intentional modification of the Goodwin Report, Judge Franks ordered an in camera review of all of the Pennsylvania State Police investigative files related to the Bear Rocks Murders, including several additional files relating to Bowen. Judge Franks ordered the Commonwealth to turn over all documents that he deemed discoverable. The Commonwealth, however, failed to turn over several critical articles of evidence to the PCRA I court for its in camera review, rendering that review incomplete. As to Bowen’s deposition testimony, Munchinski called Bowen to testify and recant his trial testimony. Bowen, however, invoked his Fifth Amendment right against self-incrimination. Judge Franks granted Bowen use immunity for his testimony. At the hearing, Bowen disavowed his deposition testimony and reaffirmed his testimony from the Retrial. Bowen subsequently committed suicide. Munehinski also adduced testimony from Kenneth Knight, an acquaintance of Bowen’s from prison. Knight testified that Bowen admitted that he was in Oklahoma at the time of the murders, and that he lied under oath during the Retrial. Further, Knight testified that he had personally introduced Bowen to Scaglione and Munehinski in March 1978, long after the Bear Rocks Murders, when all four of them were incarcerated together in Westmoreland County Jail. On August 5, 1993, based on the limited Brady violations that were known and alleged at the time, Judge Franks dismissed Munchinski’s PCRA I petition. Munchinski appealed this decision. On December 11, 1995, the Pennsylvania Superior Court affirmed the dismissal of the PCRA I petition. Munehinski sought review by the Pennsylvania Supreme Court. That Court denied allocatur on August 30,1996. On January 6,1998, Munehinski filed his first habeas petition under 28 U.S.C. § 2254. The United States District Court for the Western District of Pennsylvania dismissed the petition as untimely on September 30,1998. Munehinski appealed the dismissal of his petition to this court (the “Appeal”). On May 12, 2000, while the Appeal was pending before this court, Munehinski filed a second PCRA petition pro se. That petition raised additional Brady claims based on allegedly withheld evidence that Munehinski discovered while his first federal habeas petition was pending. Six days later, on May 18, 2000, that pro se petition was dismissed because Munehinski was still represented by counsel. On July 27, 2000, Munehinski refiled his petition through counsel (the “PCRA II” petition). The PCRA II court never reached the merits of Munchinski’s Brady claims. Rather, based on a misunderstanding of Pennsylvania law, Judge Franks erroneously concluded that the PCRA II court lacked jurisdiction over Munchinski’s petition because the Appeal remained pending in federal court. Judge Franks stated: After full review of the Petition and record, this Court finds that an appeal was filed to the United States Court of Appeals for the Third Circuit and is still pending. This Court has no jurisdiction. Defendant is not entitled to post-conviction collateral relief, and further proceedings would serve no legitimate purpose. Pa. R.Crim. P. section 1507(a). Order Dismissing PCRA II Pet., August 24, 2000, Munchinski v. Wilson, No. 07-cv-1712, ECF No. 21-12. After disclaiming jurisdiction, Judge Franks stated that Munehinski could appeal within thirty days from the date of the court’s order. Perhaps knowing that the Appeal would be resolved imminently, Munehinski declined to appeal the PCRA II Court’s decision. Instead, he heeded Judge Frank’s implicit suggestion and waited to re-file his petition after the Appeal was decided, when the state court could properly exercise jurisdiction over his petition. On January 24, 2001, we decided the Appeal, affirming the dismissal of Munchinski’s first habeas petition. C. 1. On March 21, 2001, less than sixty days after we decided the Appeal, Munehinski filed his third PCRA petition (the “PCRA III” petition). In the interim, former prosecutors Warman and Solomon had each been elevated to the bench of the Court of Common Pleas of Fayette County. This led all the sitting judges of the Court of Common Pleas of Fayette County to recuse themselves from the matter. The Administrative Office of Pennsylvania Courts assigned the PCRA III Petition to Judge Barry Feudale of the Court of Common Pleas of Northumberland County. Additionally, because of allegations of misconduct made against First Assistant District Attorney John Kopas, who represented the Commonwealth during the PCRA I proceedings, the Commonwealth’s case was taken over by the Pennsylvania Attorney General’s Office. The PCRA III petition raised several Brady claims. Munehinski twice moved to amend that petition to include additional claims based on evidence he uncovered after filing the PCRA III petition. Both of these motions were granted. In sum, Munehinski raised Brady claims based on the following eleven articles of material exculpatory evidence that were allegedly suppressed by the Commonwealth, in addition to the Goodwin Report that was the subject of the PCRA I petition: 1. Sava Addendum: an addendum to Alford’s autopsy report from Dr. Sava indicating that the semen sample taken from Alford’s rectum was of blood type “A.” Munehinski is of blood type “B.” Munehinski App’x 167. 2. Parole Revocation Documents: a set of documents related to Bowen’s 1983 parole revocation hearings evidencing a previously-undisclosed leniency agreement between Bowen, the Westmoreland County District Attorney’s Office, and the Fayette County District Attorney’s Office. Munehinski App’x 168-71. 3. Bates Report: a January 7, 1978 report from Trooper George F. Bates discussing an interview with a witness who stated that Bowen had left Pennsylvania for Oklahoma on December 1, which, if referring to December 1, 1977, would have been the day before the murders. Munehinski App’x 158. 4. Goodwin/Powell Report: a December 20, 1977 report from Goodwin in which Deputy Coroner Powell stated his belief that the anal intercourse to which Alford was subjected took place 24 hours prior to his death, thereby inconsistent with Bowen’s account of the murders. Commonwealth App’x 218. 5. Powell Addendum: a typewritten summary of a phone call from Deputy Coroner Powell reaffirming his belief, recorded in the Goodwin/Powell Report, that Alford was subjected to anal intercourse “at least 24 hours” prior to his murder. Commonwealth App’x 219. 6. Mangiacarne/Carbone Report: a December 16, 1980 report from Corporal Mangiacarne describing an interview with Elizabeth Car-bone. Carbone related a detailed confession given to her that implicated Ed Wiltrout, Commonwealth witness Dahlmann’s ex-husband. Commonwealth App’x 220. 7. Kinch Report: a December 19, 1977 report from Trooper Robert Kinch describing nail scrapings and other biological evidence that had been taken from Alford. The existence of this evidence was not disclosed to Munchinski before the First Trial or the Retrial. Commonwealth App’x 221. 8. Dunkard/Proud Report: a December 5, 1977 report from Trooper Edward Dunkard relating a discussion with Delores Proud, a dispatcher for the Mount Pleasant, Pennsylvania Police Department. According to the report, Proud received a call at approximately 2:32 A.M. on December 2, 1977, from a telephone operator who allegedly received a call from Gierke claiming that he had been shot. Proud also received a call requesting an ambulance approximately 18 minutes after Gierke’s call. The call was from Bonnie Blackson, who had discovered Alford’s body. Commonwealth App’x 223. The timing of these calls was inconsistent with the account provided by Bowen. 9.Veil/Mangello Report: a June 23, 1986 report from Trooper Richard Veil describing an interview with inmate Robert Lee Mangello, in which Mangello indicated that the Bear Rocks Murders were committed by Scaglione, Joseph Lucy, and a third, unnamed man. Commonwealth App’x 216. 10. Madden/Lucy Report: an October 15, 1986 report from Trooper William F. Madden describing an interview with Lucy, in which Lucy denied Mangello’s accusations. Lucy claimed that Mangello himself was a direct witness of the Bear Rocks Murders. Commonwealth App’x 217. 11. Bates II Report: a second copy of the Bates Report that was marked-up, allegedly by the Commonwealth. Notably, the passage “and BOWEN left on the 1st of December” was highlighted. Munchinski App’x 159. Judge Feudale held several days of hearings on the PCRA III petition. The parties presented testimony from Judge Franks, who had presided over the PCRA I petition. Judge Franks testified that, had he been aware of the Bates Report, the Goodwin/Powell Report, and the Mangiacarne/Carbone Report (i.e., had Kopas produced the entire prosecution file as per his order, rather than intentionally withholding material evidence from his in camera review), he may well have granted relief on Munchinski’s PCRA I petition. See Munchinski App’x 112. Judge Feudale also heard testimony from Warman and Trooper Goodwin about the recorded statement referenced in the Goodwin Report, that the PCRA I court concluded did not exist. Trooper Goodwin, who was at the time “serving a 10-20 year [prison] sentence for the murder of a man involved with his estranged wife,” Munchinski App’x 44, testified that he personally observed Warman recording Bowen’s statement on a tape recorder. Goodwin confirmed that the whole purpose of speaking with Bowen was to get a recorded statement, noting that without a recording “[h]e could change his story.” Munchinski App’x 96. Trooper Goodwin commented that he drafted his report the day after Bowen made his statement, and that his report was thus a timely recording of the discussion with Bowen. Finally, Trooper Goodwin noted that his report, including the reference to the recording, was approved by his supervisor, who was also present when Bowen made his statement. Trooper Goodwin noted that his supervisor would not have approved his report had such an important fact been incorrect. Warman maintained that Bowen’s statement was never tape recorded. Throughout the proceedings, Warman was openly hostile to questions. When asked why he did not approach the Court before editing the Goodwin Report, he responded that “he didn’t have to.” Munchinski App’x 102. When asked why he didn’t obtain a written statement from Bowen, he replied: “Why would I want to do that? That’s a police job, not mine.” Id. at 103. When counsel suggested that a written statement may have been a good idea because Bowen could simply disappear before trial, War-man responded “[t]hat wouldn’t be [his] problem” because he was “not the investigator .... We don’t go out and do that kind [o]f thing.” Id. at 103-04. Warman admitted that if a police officer had altered the report, the officer might be guilty of tampering with evidence, but maintained that his conduct was permissible because he was a prosecutor, not a police officer. Id. at 104. In addition to hearing testimony about the alleged recorded statement, Judge Feudale heard testimony from Kopas about his conduct during the PCRA I proceedings. Kopas acknowledged that he confirmed to the PCRA I court, “[a]s an Officer of the Court,” that he submitted the entire police file to Judge Franks for in camera review. Munchinski App’x 108. He could not explain why the files he turned over “included none of the eleven pieces of exculpatory evidence at issue.” Id. Throughout the hearing, Kopas was evasive. Kopas repeatedly responded to questions by stating that he could not or did not recall the requested information. Judge Feudale noted that in contrast to his statements during the PCRA I hearings, Kopas’s testimony in the PCRA III hearings was couched in “equivocal language.” Id. Finally, based on the Kinch Report’s references to several articles of physical evidence that were never submitted for laboratory testing, the PCRA III Court ordered testing of all evidence still in existence. The test results were inconclusive, and were matched either to the victims or an unidentifiable male. On October 1, 2004, Judge Feudale filed a strongly-worded 114-page opinion thoroughly analyzing the merits of the PCRA III petition, and granting Munchinski’s petition. At the outset of his opinion, Judge Feudale remarked on the nature of the Brady claims in this case: As a general observation, in the past seventeen years we have presided over numerous PCRA petitions, both counseled and uncounseled. Incantations of prosecutorial/police misconduct, corruption and perjury along with utterances of egregious and outrageous [sic], often appeared formulaic, and were ostensibly an elevation of form over substance. At a minimum, the circumstances surrounding these homicides, and the subsequent events involving the principal cast of characters in this tragic drama lend themselves to the term extraordinary. Munchinski’s App’x 40. The PCRA III court concluded that: (1) despite the PCRA I Court’s conclusion to the contrary, the recorded statement referred to in the omitted paragraph of the Goodwin Report did exist, and was intentionally withheld by prosecutors; (2) even if no recorded statement existed, War-man’s intentional editing of the Goodwin Report violated Brady; (3) Kopas intentionally committed prosecutorial misconduct in violation of Brady when he failed to turn over the entire police file, as ordered during the PCRA I proceedings; (4) Solomon and Warman both committed prosecutorial misconduct and numerous Brady violations leading up to and during the First Trial and the Retrial; and (5) Warman intentionally misled the jury during the Retrial when he stated that all Bowen received in exchange for his testimony was immunity, because he was aware that Bowen also received leniency as to a number- of probation and parole violations in Westmoreland County. The PCRA III court also concluded that the evidence withheld by prosecutors was material under Brady, and granted Munchinski’s petition. The court concluded that Warman, Solomon, and Kopas all engaged in serious and intentional prosecutorial misconduct. Judge Feudale declined to refer the former prosecutors to the Judicial Conduct Board or for possible criminal charges because such a referral was not “within the clear ambit of relief set forth in Section 9546 of the [PCRA].” Munchinski App’x 33. In a footnote to his order, Judge Feudale excoriated Warman, Solomon, and Kopas, stating that their “actions ill served the victims, their families, the defendant and citizens of Fayette County,” and suggesting that the outcome of the case was “a reflection of the ongoing foundation of prosecutorial misconduct by the former prosecutors.” Munchinski App’x 32. Judge Feudale commented that in his “17 years as a judge, while [he has] handled numerous PCRA’s [sic], and granted collateral relief, this is the first time [he has] granted a request for new trial/discharge.” Id. Judge Feudale closed by characterizing the matter before him as “an extraordinary case” and expressing the hope “that [it] is not replicated[.]” Id. at 33. 2. On October 8, 2004, the Commonwealth appealed from the PCRA III court’s grant of relief to Munchinski. On December 14, 2005, the Pennsylvania Superior Court issued a nonprecedential and unsigned memorandum opinion reversing the PCRA III court. Because the Superior Court’s opinion is the focus of our review, we will subject it to painstaking analysis. Unfortunately, though the Superior Court’s opinion is lengthy, its reasoning is opaque. The memorandum is confusing, and at times internally inconsistent. As best we can understand, the Superior Court concluded that certain articles of evidence listed in the PCRA III petition as undisclosed by the prosecution were not raised on a timely basis, and thus could not be raised as independent claims. Nonetheless, because some of Munchinski’s claims were timely, the court concluded that it was required to consider all of the evidence raised in the PCRA III petition. In analyzing the merits of Munchinski’s Brady claims, the court considered each article of evidence in isolation, never considering the aggregate materiality of all of the withheld evidence. The Superior Court began its opinion with a discussion of the jurisdictional restrictions on courts reviewing a PCRA petition, noting that “Pennsylvania courts have no jurisdiction to address claims in an untimely PCRA petition no matter how serious the assertions raised therein[.]” App’x 113. Munchinski argued that his petition was timely under Pennsylvania’s “after-discovered evidence exception.” App’x 116-18; 42 Pa. Cons.Stat. Ann. § 9545(b)(2) (after-discovered evidence exception). The Superior Court suggested that some of Munchinski’s claims were filed beyond the sixty-day limitations period for after-discovered evidence. Significantly, the Court’s analysis did not end there. Up to this point in the opinion, the Superior Court had not considered the articles of evidence that were discovered between the filing of Munchinski’s PCRA II petition and his PCRA III petition. Munchinski discovered a report of Sergeant George Fayouk’s interview of Richard Bowen between February 20, 2003 and March 10, 2003. The court concluded that Munchinski “asserted the claims based thereon within sixty days of its discovery. Thus all such claims are timely.” App’x 133. Additionally, the court noted that Munchinski timely raised the Veil/Mangello Report and the Madden/Lucy Report. As such, the court “agree[d] with the third PCRA court that Munchinski raised cognizable Brady claims.” App’x 139. In a critical paragraph, the Superior Court stated: We shall address the Commonwealth’s contentions [that the alleged Brady violations did not concern “material” evidence] seriatim. Before doing so, however, we must resolve the question of whether the procedural irregularities of this case preclude us from considering all of the evidence in the certified record. We conclude that we cannot confine our analysis only to newly acquired evidence that was timely presented. Rather, the distinction that must be made is whether a particular claim is timely and whether that claim is supported by sufficient evidence of record, no matter when that evidence was acquired. Because the PCRA’s timing restrictions are jurisdictional, this Court lacks authority to affirm an order granting relief predicated on an untimely claim merely because certain timely presented after-discovered evidence tends to support that claim. Conversely, however, a timely asserted claim cannot be found to be invalid simply because part of the evidence that supports the PCRA court’s ruling was submitted too late to form the basis of an entirely separate claim. In short, we cannot review the PCRA court’s rulings on a diminished record. App’x 148-49. The Superior Court proceeded to reach the merits of all of the articles of evidence cited in the PCRA III petition, with the exception of the recorded statement referenced in the Goodwin Report — an issue that was “previously litigated” by the PCRA I court. The Superior Court reiterated its conclusion that it was required to consider the merits as to all of the individual articles of evidence, including those articles that would have been untimely if raised separately: Nevertheless, the third PCRA court’s grant of relief did not rely only on the eleven pieces of purported newly-discovered evidence, which were untimely asserted. We must therefore discuss all of the evidence on which that court relied in granting relief. See [Commonwealth v.] Santiago, [439 Pa.Super. 447,] 654 A.2d [1062] at 1070 [(1994)] (holding that an appellate court must evaluate the significance of suppressed evidence pursuant to Brady in relation to the record as a whole). As noted above, there is a distinction to be made between a claim that is untimely under the PCRA and a timely claim predicated on evidence that has been presented too late to create a separate issue. App’x 162-63. The relationship between the court’s discussion of the timeliness of Munchinski’s claims and its discussion of the merits of Munchinski’s claims is unclear. Nothing in the opinion suggests that the court’s ruling on the merits was in the alternative. Indeed, the opinion suggests the opposite — that under Pennsylvania law, the court was required to consider all of the evidence listed in Munchinski’s petition, even if some of that evidence would have been untimely in a separate petition. At all events, the Superior Court reversed the PCRA III court and dismissed the PCRA III petition. Munchinski sought review from the Pennsylvania Supreme Court, but on February 8, 2007, that court denied allocatur. 3. On December 15, 2007, Munchinski filed the instant habeas petition in the United States District Court for the Western District of Pennsylvania. The District Court concluded that this petition was a “second or successive petition” within the meaning of 28 U.S.C. § 2244(b), and transferred jurisdiction over the case to this court pursuant to 28 U.S.C. § 1631. On November 5, 2009, we concluded that Munchinski presented “a prima facie showing that his petition contained] newly discovered evidence” as required under § 2244(b), and transferred jurisdiction over the petition back to the District Court. On August 5, 2011, the Magistrate Judge to whom this matter was assigned issued a thorough 80-page opinion granting Munchinski’s habeas petition. Aware of the arguments over whether Munchinski had properly complied with state and federal procedural requirements,- the District Court first considered whether Munchinski’s petition was timely under the Antiterrorism and Effective Death Penalty Act of 1996, Pub. L. No. 104-132, 110 Stat. 1214 (1996), which requires that claims based on newly-discovered evidence be filed within one year of the discovery of that evidence. The court found that the majority of the eleven articles of newly-discovered evidence, with the exception of the Veil/Mangello Report, the Madden/Lucy Report, and the Bates Report II, were raised beyond the one year statute of limitations in § 2244(d)(1)(D). Though untimely, the District Court equitably tolled the one-year statute of limitations for the majority of these articles of evidence, with the exception of the Sava Addendum, the Parole Revocation Documents, and the Goodwin Report, which were discovered prior to the filing of the PCRA I petition. The court reasoned that the uncertainty in the Pennsylvania State Courts surrounding parallel petitions for post-conviction relief in both state and federal courts was a sufficiently extraordinary circumstance to justify equitable tolling given “the general diligence exhibited by [Munchinski] throughout this ordeal[.]” Commonwealth App’x 40. The court then considered whether Munchinski had procedurally defaulted his claims. The court appears to have assumed that there was procedural default. The bulk of the court’s analysis focused on whether default could be excused. The court acknowledged that a procedural default can be excused for one of two reasons: (1) if a petitioner can show cause for the default and prejudice resulting therefrom; or (2) if enforcing the procedural default rule would effect a fundamental miscarriage of justice. The court declined to consider whether Munchinski had shown cause and prejudice, because “he so clearly qualifies for the second exception to the procedural default rule — i.e., failing to allow his claims to proceed would result in a fundamental miscarriage of justice.” Commonwealth App’x 46. Specifically, the court concluded that a fundamental miscarriage of justice would occur because “he has show[n] by ‘clear and convincing evidence that, but for constitutional error, no reasonable factfinder would have found the applicant guilty of the underlying offense.’ ” Commonwealth App’x 46 (quoting 28 U.S.C. § 2244(b) (2) (B) (ii)). Finally, the District Court reached the merits of Munchinski’s Brady claims. The District Court concluded that the Superior Court unreasonably applied Brady in violation of 28 U.S.C. § 2254(d)(1), because the court analyzed the materiality of the withheld evidence individually, rather than collectively. See Kyles v. Whitley, 514 U.S. 419, 437-38, 115 S.Ct. 1555, 131 L.Ed.2d 490 (1995). The court further concluded that Munchinski’s new evidence demonstrated that no reasonable juror would have found him guilty under the high standard required of a habeas petitioner filing a second or successive petition under 28 U.S.C. § 2244(b)(2). The District Court granted Munchinski habeas relief, permitting the Commonwealth 120 days from the filing of its order in which it could retry Munchinski. The District Court also ruled that it would stay its order if either party chose to appeal. On September 2, 2011, the Commonwealth timely appealed. II. The Commonwealth raises three arguments on appeal: (1) that the District Court erred by equitably tolling AEDPA’s one-year statute of limitations; (2) that Munchinski procedurally defaulted certain claims, and the District Court erred by excusing the default on the grounds of fundamental miscarriage of justice grounds; and (3) that Munchinski failed to demonstrate his actual innocence under the high standard required by § 2244(b) (2) (B) (ii). The District Court had jurisdiction over Munchinski’s petition pursuant to 28 U.S.C. §§ 2241 & 2254. We have jurisdiction over this appeal pursuant to 28 U.S.C. §§ 1291 & 2253. A. 1. Under AEDPA, “[a] 1-year period of limitation shall apply to an application for a writ of habeas corpus by a person in custody pursuant to the judgment of a State court.” 28 U.S.C. § 2244(d). For a petitioner asserting claims based on newly-discovered evidence, the limitations period generally will begin to run on “the date on which the factual predicate of the claim or claims presented could have been discovered through the exercise of due diligence.” Id. § 2244(d)(1)(D). AEDPA provides that the one-year limitation period is subject to “statutory tolling”: “[t]he time during which a properly filed application for State post-conviction or other collateral review with respect to the pertinent judgment or claim is pending shall not be counted toward any period of limitation under this subsection.” Id. § 2244(d)(2). AEDPA’s statute of limitations must be applied “on a claim-by-claim basis.” Fielder v. Varner, 379 F.3d 113, 118 (3d Cir.2004). The District Court divided the alleged Brady violations into three separate groups based on “the date on which the factual predicate of the claim ... presented could have been discovered through the exercise of due diligence.” Id. § 2244(d)(1)(D). For each group, the District Court properly applied a two-step analysis to determine whether the claims were timely under § 2244(d)(1). First, the court considered whether more than one year had elapsed between the date on which the relevant evidence could have been discovered through the exercise of due diligence. If more than one year had elapsed, the court then considered whether the group of claims was entitled to statutory tolling pursuant to § 2244(d)(2). The Group 1 claims are based on the Veil/Mangello Report, the Madden/Lucy Report, and the Bates II Report. This evidence was discovered on March 10, 2003, while the PCRA III petition was pending. The instant habeas petition was filed on December 15, 2007. More than one year lapsed from the date of discovery until the date Munchinski’s habeas petition was filed, rendering the Group 1 claims untimely under § 2244(d)(1). On April 15, 2003, however, Munchinski filed his PCRA III petition in Pennsylvania state court. The Superior Court found that the Brady violations in Group 1 were properly filed. Thus, from April 15, 2003 until February 8, 2007, when the Pennsylvania Supreme Court denied Munchinski’s request for allocatur, there was a properly filed PCRA petition pending in the state court system. As a result, Munehinski is entitled to statutory tolling for this period pursuant to § 2244(d)(2). This means that the statute of limitations for the Group 1 claims ran from March 10, 2003 until April 15, 2003, and then from February 8, 2007 until December 15, 2007. Cumulatively, these periods are shorter than one year. The Group 1 claims are therefore timely under § 2244. The Group 2 claims are based on the Goodwin Report, the Sava Report, and the Parole Revocation Documents. This evidence was discovered prior to the filing of Munchinski’s PCRA I petition. Given that we previously held these claims untimely in Munchinski’s first habeas petition, Munchinski v. Price, 254 F.3d 1078 (3d Cir. 2001) (unpublished), the District Court concluded that these claims are also untimely in the instant petition. We agree, and conclude that the Group 2 claims are untimely under § 2244(d). Finally, the Group 3 claims are based on: (1) the Bates Report; (2) the Goodwin/Powell Report; (3) the Powell Addendum; (4) the Mangiacarne/Carbone Report; (5) the Dunkard/Proud Report; and (6) the Kinch Report. This evidence was discovered at an unspecified time in 2000, while Munchinski’s appeal from the denial of his first federal habeas petition was pending before this court. The District Court concluded that the Bates Report was discovered on or before May 12, 2000, when Munehinski filed his pro se PCRA II petition referencing the Bates Report. Again, well over a year elapsed between the discovery of the report and the filing of the instant habeas petition; that particular claim is thus untimely under § 2244(d)(1). The court credited Munchinski’s assertion that the remaining evidence in Group 3 was discovered between July 27, 2000 and August 24, 2000. Using the July 27, 2000 date as the date of discovery, the Group 3 claims are also untimely under § 2244(d)(1). Nor are the Group 3 claims entitled to statutory tolling under § 2244(d)(2). The PCRA II court dismissed the PCRA II petition, first for being filed pro se, and second for lack of jurisdiction. As such, the petition was never “properly filed” within the meaning of § 2244(d)(2). See Artuz v. Bennett, 531 U.S. 4, 8, 121 S.Ct. 361, 148 L.Ed.2d 213 (2000). Similarly, the Superior Court reviewing Munchinski’s PCRA III petition concluded that the Brady allegations premised on the evidence in Group 3 were not raised within 60 days of the date of discovery, as required by Pennsylvania law. As such, the PCRA III petition was also not “properly filed” within the meaning of § 2244(d)(2). Thus, the Group 3 claims are untimely under § 2244(d). 2. Though the Group 2 and 3 claims are untimely under § 2244(d), the Supreme Court has held that § 2244(d) “is not ‘jurisdictional’” and does not set forth “an inflexible rule requiring dismissal ... [whenever the] clock has run.” Day v. McDonough, 547 U.S. 198, 205, 208, 126 S.Ct. 1675, 164 L.Ed.2d 376 (2006). Rather, “§ 2244(d) is subject to equitable tolling in appropriate eases.” Holland v. Florida, — U.S. -, 130 S.Ct. 2549, 2560, 177 L.Ed.2d 130 (2010). The decision to equitably toll § 2244(d) “must be made on a case-by-case basis.” Id. at 2563 (quoting Baggett v. Bullitt, 377 U.S. 360, 375, 84 S.Ct. 1316, 12 L.Ed.2d 377 (1964)). “In each case, there is a need for ‘flexibility,’ ‘avoiding mechanical rules,’ and ‘awareness ... that specific circumstances, often hard to predict in advance, could warrant special treatment in an appropriate case.’ ” Pabon v. Mahanoy, 654 F.3d 385, 399 (3d Cir.2011) (quoting Holland, 130 S.Ct. at 2563). There are “no bright lines in determining whether equitable tolling is warranted in a given case.” Id. Rather, equitable tolling is appropriate when “principles of equity would make the rigid application of a limitation period unfair.” Miller v. N.J. State Dep’t of Corr., 145 F.3d 616, 618 (3d Cir.1998) (alterations omitted). Generally speaking, a petitioner is entitled to tolling if he shows: (1) “ ‘that some extraordinary circumstance stood in his way’ and prevented timely filing”; and (2) that “he has been pursuing his rights diligently.” Id. at 2562 (quoting Pace v. DiGuglielmo, 544 U.S. 408, 418, 125 S.Ct. 1807, 161 L.Ed.2d 669 (2005)). Initially, we agree with the District Court that the Group 2 claims are not eligible for equitable tolling. The parties do not object to this conclusion. The Commonwealth’s argument focuses on the Group 3 claims. The District Court concluded that the Group 3 claims were eligible for equitable tolling because the PCRA II court’s erroneous dismissal of the PCRA II petition constitutes an extraordinary circumstance, and because Munchinski diligently pursued his rights despite his circumstances. (a) The Commonwealth first challenges the District Court’s conclusion that there were extraordinary circumstances that prevented Munchinski from timely filing the instant habeas petition. When the facts allegedly constituting an extraordinary circumstance are not in dispute, “a District Court’s decision on the question whether a case is sufficiently ‘extraordinary ’ to justify equitable tolling should be reviewed de novo.” Brinson v. Vaughn, 398 F.3d 225, 230 (3d Cir.2005). The extraordinary circumstances prong requires that the petitioner “in some extraordinary way be[ ] prevented from asserting his or her rights.” Brown v. Shannon, 322 F.3d 768, 773 (3d Cir.2003). “One ... potentially extraordinary situation is where a court has misled a party regarding the steps that the party needs to take to preserve a claim.” Brinson, 398 F.3d at 230. That is precisely what happened here. The facts before us are remarkably similar to those in Urcinoli v. Cathel, 546 F.3d 269, 273 (3d Cir. 2008). In both cases, a court erroneously dismissed pending petitions amidst confusion over recent caselaw. In both cases, the court implicitly suggested steps that the petitioner should take to present the same claims in the future. In Urcinoli, the court dismissed a so-called “mixed” habeas petition containing both exhausted and unexhausted claims, and implicitly suggested that the petitioner refile the same petition without the allegedly unexhausted claims. As we noted, however, if the petitioner refiled the petition, those claims would have been untimely because the one-year limitation in § 2244(d) had already passed. Id. So too here, the PCRA II court erroneously dismissed the PCRA II petition for lack of jurisdiction because of Munchinski’s pending federal appeal. In so doing, the court implied that Munchinski could reassert his claims once the federal appeal was resolved. Munchinski did precisely that, but the Superior Court concluded that such claims had become untimely. We thus conclude, as we did in Urcinoli, that the PCRA II court’s dismissal of Munchinski’s pending petition, with its implicit suggestion that Munchinski refile once his federal appeal was resolved, was sufficiently misleading as to constitute an extraordinary circumstance because “it later operate[d] to prevent [Munchinski] from pursuing his rights.” Id. at 275. (b) The diligence required of a habeas petitioner seeking equitable tolling “is reasonable diligence, not maximum feasible diligence.” Holland, 130 S.Ct. at 2565 (internal quotation marks and citations omitted). The Commonwealth argues that by failing to appeal the PCRA II court’s erroneous dismissal of his petition, Munchinski did not demonstrate the “reasonable diligence” necessary to permit equitable tolling. We have not addressed the appropriate standard of review for a District Court’s determination that a habeas petitioner demonstrated reasonable diligence. Whether a petitioner’s diligence was “reasonable” under the circumstances of the case seems a much more fact-intensive inquiry than whether a set of undisputed facts constitutes an “extraordinary circumstance” as a matter of law. As such, Brinson’s reasons for de novo review of a district court’s extraordinary circumstances analysis may not apply to its diligence analysis in all cases. See, e.g., Rivas v. Fischer, 687 F.3d 514, 539-40 (2d Cir.2012) (reviewing district court’s diligence analysis for clear error). Indeed, when reviewing a district court’s determination that a petitioner demonstrated “reasonable diligence in the circumstances” under § 2244(d)(1)(D), we apply a clear error standard. Wilson v. Beard, 426 F.3d 653, 660-61 (3d Cir.2005). We need not decide this issue, however, because we conclude that Munchinski demonstrated reasonable diligence even under a de novo standard. The diligence requirement “does not demand a showing that the petitioner left no stone unturned.” Ramos-Martinez v. United States, 638 F.3d 315, 324 (1st Cir.2011). Rather, “[t]o determine if a petitioner has been [reasonably] diligent in pursuing his petition, courts consider the petitioner’s overall level of care and caution in light of his or her particular circumstances.” Doe v. Busby, 661 F.3d 1001, 1013 (9th Cir.2011); see also Schlueter v. Varner, 384 F.3d 69, 74 (3d Cir.2004) (“Due diligence ... require^] reasonable diligence in the eircumstances.”)- In other words, the diligence inquiry is fact-specific and depends on the circumstances faced by the particular petitioner; there are no bright line rules as to what conduct is insufficient to constitute reasonable diligence. If a petitioner “did what he reasonably thought was necessary to preserve his rights ... based on information he received ..., then he can hardly be faulted for not acting more ‘diligently’ than he did.” Holmes v. Spencer, 685 F.3d 51, 65 (1st Cir.2012). Over the past several decades, Munchinski has vigorously pursued relief in state and federal courts. He has filed five petitions for post-conviction relief, all raising substantial and difficult questions about his conviction. He filed the PCRA II petition very soon after discovering the Bates Report, though the petition was mistakenly dismissed by the court. He followed the PCRA II court’s implicit suggestion and filed his PCRA III petition within a month of our dismissal of the Appeal, when the alleged jurisdictional issue had been resolved. Throughout this process, he continued to collect evidence. He presented this evidence in his PCRA III petition — if the PCRA II court had been correct about the jurisdictional issue, this evidence would have been timely presented under 42 Pa. Cons.Stat. Ann. § 9545(b)(2). Under the circumstances, we conclude that Munchinski was reasonably diligent. Munchinski’s conduct is comparable to that of the petitioner in Mathis v. Thaler, 616 F.3d 461 (5th Cir.2010). In that case, the petitioner was simultaneously pursuing post-conviction relief in state and federal courts. Just like the PCRA II court, the state court erroneously dismissed the pending state court petition based on its understanding of Texas’s so-called “two-forum rule,” which prohibited state courts from exercising jurisdiction over a state court petition while a federal petition was pending. The Texas state courts subsequently clarified the two-forum rule in Ex parte Soffar, 143 S.W.3d 804, 807 (Tex. Crim.Ct.App.2004), permitting review of a state court petition if the federal petition was stayed. Soon after the Soffar decision, the petitioner again sought relief in the state courts. The Fifth Circuit concluded that the petitioner “exhibited a pattern of diligently pursuing his rights in state and federal court, despite procedural difficulties .... Far from sleeping on his rights, [the petitioner] sought relief in multiple tribunals in an effort to raise his ... claim. Under the circumstances, [the petitioner’s] actions were more than reasonably diligent.” Mathis, 616 F.3d at 474. We reach the same conclusion here, and agree with the District Court that in view of the extraordinarily difficult circumstances that Munchinski faced, he demonstrated reasonable diligence in pursuing his rights. The Commonwealth argues that Munchinski’s failure to appeal from the PCRA II court’s dismissal of his petition precludes him from showing reasonable diligence. We disagree. Although with the benefit of hindsight, an appeal may have been prudent, equitable tolling does not require the “maximum feasible diligence.” Holland, 130 S.Ct. at 2565. What the diligence inquiry requires is reasonable diligence under the circumstances of a particular case. The PCRA II court interpreted Pennsylvania state law as precluding jurisdiction over a PCRA petition while Munchinski’s federal appeal remained pending. As the District Court noted, at that time the Pennsylvania Supreme Court had yet to issue its ruling in Commonwealth v. Whitney, 572 Pa. 468, 817 A.2d 473 (2003), which clarified that Pennsylvania state courts do maintain jurisdiction over a PCRA petition despite a pending federal petition. As such, when the PCRA II court dismissed Munchinski’s petition, it was not clear that the court had erred. The Pennsylvania Supreme Court’s case law could be read (as it was by the PCRA II court) to disclaim jurisdiction over a PCRA petition while a federal petition was pending. There then existed no case law that might clearly indicate to Munchinski that the PCRA II court had erred. Given the uncertainty surrounding the issue, we do not think it was unreasonable for Munchinski to choose to credit the PCRA II court’s interpretation of Pennsylvania procedural law, and heed its implicit suggestion that he wait to refile his claims once this court resolved his federal appeal. As we have observed, the diligence inquiry is contextual. Here, Munchinski made almost every effort to seek timely post-conviction relief in both the state and federal systems. He simply chose to follow the implicit suggestion from the PCRA II court rather than appeal its decision. He did not “sleep[ ] on his rights.” Mathis, 616 F.3d at 474. Nor did he simply misread a court opinion. See Sistrunk v. Rozum, 674 F.3d 181, 190 (3d Cir.2012) (holding that “misreading a court opinion” was not a sufficient basis to permit equitable tolling). He did exactly what the PCRA II court implicitly suggested, doing “what he reasonably thought was necessary to preserve his rights ... based on information he received!.]” Holmes, 685 F.3d at 65. Under these circumstances, the “principles of equity would make the rigid application of a limitation period unfair.” Miller, 145 F.3d at 618 (alterations omitted). We thus conclude that Munchinski was reasonably diligent under the circumstances in pursuing his rights. Because we conclude that Munchinski faced extraordinary circumstances and demonstrated reasonable diligence in pursuit of his rights, we agree with the District Court that he is entitled to equitable tolling. The District Court was correct in deciding to toll the statute of limitations as to his Group 3 claims from August 24, 2000, when Munchinski’s PCRA II petition was dismissed, until February 8, 2007, when the Pennsylvania Supreme Court denied allocatur over the Superior Court’s dismissal of his PCRA III petition. With this period equitably tolled, Munchinski’s Group 3 claims, with the exception of his claim based on the Bates Report, are timely. As such, the District Court could properly consider the Group 1 and Group 3 claims, again with the exception of the claim based on the Bates Report. B. Even if a claim is timely under § 2244, a federal court “may not conduct habeas corpus review of a claim which a petitioner has procedurally defaulted in state court.” Lark v. See’y Pa. Dep’t of Corr., 645 F.3d 596, 611 (3d Cir.2011). Grounded in principles of comity and federalism, the procedural default doctrine prevents a federal c
